Side-pressure type safety cap

ABSTRACT

According to the present invention, a side-pressure type safety cap is threaded onto an upper portion of a container body containing contents therein, so as to open/close the outlet of the container. The safety cap of the present invention is configured to be opened only when a joint protrusion and a rotating protrusion contact each other by pressure being applied to the sides of an outer cap. Thus, a child unable to perceive such a configuration cannot open the cap, thereby preventing the child from ingesting harmful substances, and the contents in the container from being unnecessarily wasted.

TECHNICAL FIELD

The present invention relates to a side-pressure type safety cap, and inparticular to a side-pressure type safety cap which is configured for acap to be opened and closed only when an engaging protrusion and arotating protrusion come into contact with each other by a side pressureof an outer cap, so a kid is prevented from eating a harmful substanceto a human body by preventing a kid, who does not know what is in thecontainer, from opening the cap, so unnecessary consumption of thecontents stored in the container can be prevented.

BACKGROUND ART

A cap is generally designed to prevent the contents stored in acontainer body from discharging to the outside as it is capped at thetop of the container body while preventing contamination of contents.

The above mentioned cap is so designed that anyone can easily open andclose as it rotates on one or the other direction because it is screwedto the threads of a container body. With this construction, a kid wholacks discernment may open easily the cap thus spilling the contents,which results in over consumption of the contents. In particular, incase that the container body stores contents harmful to a human body, akid may drink the contents without knowing what is in the containerbody, so a serious accident may happen.

In order to improve the above mentioned problems, there are provided astructure featuring in that the cap can be opened only when the top ofthe cap is pressed downward, and a structure featuring in that the capcan be opened only when both sides of the cap are pressurized for thekid not to easily open the cap.

The conventional safety cap will be described with reference to “Bottleassembly preventing children from opening” of the utility modelregistration number 0318864. The above mentioned utility modelregistration of the safety cap is characterized in that there isprovided a container assembly formed of a hollow container body part ofthe top of which is open, and a cap 20 covering the opening of thecontainer body. The container body 10 comprises a neck 14 extending witha diameter smaller than the other portions of the container, an outlet11 formed as the top of the neck 14 is open, a male engaging screw 12protruded from the surrounding of the neck 14, a flange 13 extendingalong the surrounding of the neck 4 as much as a certain width in anouter radial direction, and an engaging protrusion 15 protruded from thetop of the flange 13. The cap 20 comprises an upper side engagingprotrusion 25 formed at the inner wall surface while corresponding tothe engaging protrusion 15, an inner cap 23 with the inner diametermatching the outer diameter of the outlet 11, and a female engagingscrew 22 protruding from the inner wall surface of the inner cap 23while corresponding to the male engaging screw 12.

The conventional safety cap 20 forms a flange 13 at the container body10 so as to form an engaging protrusion 15 butting with the upper sideengaging protrusion 5 formed in the interior of the cap 20 when openingthe cap 20, and the engaging protrusion 15 formed at the top of theflange 13, so the construction of the container body 10 seemscomplicated, which makes it impossible to obtain the role of the safetycap when engaging the cap 20 to various containers with only threads.

DISCLOSURE OF INVENTION

Accordingly, the present invention is made to improve the abovementioned problems encountered in the conventional art and otherproblems. It is an object of the present invention to provide a sidepressure type safety cap which is configured for a cap to be opened andclosed only when an engaging protrusion and a rotating protrusion comeinto contact with each other by a side pressure of an outer cap, so akid is prevented from eating a harmful substance to a human body bypreventing a kid, who does not know what is in the container, fromopening the cap, so unnecessary consumption of the contents stored inthe container can be prevented.

When the cap rotates as the engaging protrusion of the inner cap therotating protrusion of the outer cap are engaged and rotate, the threadsformed at the inner surface of the inner cap are thread-engaged with thethreads of the container body, so the cap can be opened and closed. Theabove mentioned construction can be well applied to all the containerswith threads.

To achieve the above objects, there is provided a side press type safetycap in a safety cap which is thread engaged onto the top of a containerbody which stores contents, for thereby opening and closing an outlet ofthe container; an inner cap which has threads at its inner surface forsurrounding and thread-engaging the top of the container body, aplurality of regularly spaced engaging protrusions formed at its outersurface and surrounding the same; an outer cap which surrounds andengages the inner cap and has a rotating protrusion which protrudes frombetween the plurality of the engaging protrusions at each side of theinner surface and is engaged with the engaging protrusion and rotatesthe inner cap.

In addition, the engaging protrusion comprises an engaging protrusionportion protruded forward from the outer surface of the inner cap; and abent part which is bent in one direction from an end portion of aprotrusion piece.

In addition, the bent part comprises a slope surface which is gently inthe direction of the end portion, going farther from an outer surface ofthe inner cap.

BEST MODES FOR CARRYING OUT THE INVENTION

The present invention will be described with reference to theaccompanying drawings. It is noted that the same reference numeralsappearing in each drawing means the same elements.

FIG. 1 is a disassembled perspective view illustrating a construction ofa side pressure type safety cap according to a preferred embodiment ofthe present invention. FIG. 2 is an engaged cross sectional viewillustrating a construction of a side pressure type safety cap accordingto a preferred embodiment of the present invention. FIG. 3 is a crosssectional view illustrating a press indication part of a side pressuretype safety cap according to a preferred embodiment of the presentinvention.

FIGS. 4 and 5 are views illustrating an opening and closing state on thebasis of an engagement of an inner cap and an outer cap of a sidepressure type safety cap according to a preferred embodiment of thepresent invention.

As shown in FIGS. 1 to 5, the side pressure type safety cap according toa preferred embodiment of the present invention comprises an inner cap100 and an outer cap 200.

The inner cap 100 is thread engaged to the thread 11 formed at the topof the container body 10 configured to store contents and has a thread110 formed at its inner surface for the thread engagement with thethread 11.

In the present invention, a plurality of regularly spaced engagingprotrusions 120 are formed along the outer surface of the inner cap 100.The engaging protrusion 120 comprises a protrusion piece 121 protrudingforward from the outer surface of the inner cap 100, and a bent part 122bent in one direction at the end of the inner cap 100.

The engaging protrusion 120 is formed in an inverted L-shaped andconsists of a protrusion piece 121 and a bent part 122. During therotation of the outer cap 200, the front end 120 a and the terminal part120 b of the engaging protrusion 120 are engaged with the rotationprotrusion 210 for thereby opening and closing the safety cap.

Meanwhile, the bent part 122 has a slope surface which becomes gentle inthe direction of the end portion, going farther from the outer surfaceof the inner cap 100. When it is intended to close the safety cap byrotating the outer cap 200, the rotation protrusion 210 is engaged withthe terminal part 120 b of the engaging protrusion 120, so the inner cap100 can rotate together.

The outer cap 200 allows the inner cap 100 to rotate in engagement withthe engaging protrusion 120 depending on the rotations while the outercap 200 is engaged with the inner cap 100 while surrounding the same. Inthe present invention, at each side of the inner surface of the outercap 200 is provided a rotation protrusion 210 protruding between theengaging protrusion 120.

One surface of the rotation protrusion 210 is formed of a gentle slope,the other surface having a sharp slope of about 90°, so the rotationprotrusion 210 is engaged with either the front end 120 a or theterminal part 120 b of the engaging protrusion 120 depending on therotations one direction or the other direction of the outer cap 200.

At the rotation protrusion 210 is formed a mounting groove 211 for thefront end 120 a of the engaging protrusion 120 to mounts therein. Whenrotating the outer cap 200 by pressing each side of the same, the frontpart 120 a of the engaging protrusion 120 is mounted in the mountinggroove 211, and the inner cap 100 comes to rotate together with theouter cap 200, so the safety cap can be opened.

At the outer cap 200 is formed a press indication part 220 indicating apressed portion in the outer surface facing the rotation protrusion 210for a user to rotate the outer cap 200 while pressing the same.

Referring to FIGS. 4 and 5, the opening and closing operations of theside press type safety cap according to a preferred embodiment of thepresent invention will be described.

FIGS. 4 and 5 are views illustrating an opening and closing state on thebasis of an engagement of an inner cap and an outer cap of a sidepressure type safety cap according to a preferred embodiment of thepresent invention.

As shown in FIG. 4, when it needs to close the side press type safetycap according to a preferred embodiment of the present invention,holding the outer cap 200 the user rotates the outer cap 200 in theclosing direction. When the rotation of the outer cap 200 is finished,the rotation protrusion 210 protruded from each side of the innersurface of the outer cap 200 rotates together. As the rotationprotrusion 210 rotates, the other surface which corresponds to a sharpslope of the rotation protrusion 210 becomes engaged with the terminalpart 120 b of the engaging protrusion 120 and allows the inner cap 100to rotate. Therefore, the user can close the cap in the same way asclosing the common thread type cap onto the container body.

As shown in FIG. 5, when it needs to open the side press type safety capaccording to a preferred embodiment of the present invention, the userrotates the outer cap 200 in the opening direction in a state that thepress indication part 220 of the outer cap 200 is pressed. When thepress indication part 220 is pressed, each side of the outer cal 200where the rotation protrusion 210 is formed is dented a little. When theouter cap 200 is rotated in the opening direction, the rotatingprotrusion 210 of the outer cap 200 is engaged with the front end 120 aof the engaging protrusion 120, so the inner cap 100 can rotatetogether, thus opening the safety cap.

When the outer cap 200 is rotated in a state that the press indicationpart 220 is no pressed when opening the safety cap, the engagingprotrusion 120 and the rotating protrusion 210 idle rotate thanks to thespace between the engaging protrusion 120 and the rotating protrusion210. Therefore, the inner cap 100 does not rotate, and the safety capdoes not open.
